SUPPORTING-LEG FOR SUPERPOSING WIRE TRAYS.

Application filed April 25, 1921.

T 0 all whom it may concern.

Be it known that I, FRANK M. SNYDER, a citizen of the United States,residing at La Fayette, in the county of Tippecanoe and State ofIndiana, have invented a new and useful Supporting-Leg for SuperposingWire Trays, of which the following is a specification.

It is the object of my invention to superpose ordinary wire trays, suchas letter trays, by a simple and inexpensive superposing device whichcan be applied to any wire tray and which holds the trays firmly in thedesired relationship to each other.

The accompanying drawing illustrates my invention: Figure 1 is aperspective View of two wire trays one superposed on the other by myimproved superposing legs; Fig. 2 is an enlarged detail of one of thesuperposing legs, and a corner fragment of an upper tray carried by thesuperposing legs; and Fig. 3 is a perspective view of one of the cornerpieces provided at lower tray, for receiving the lower end of asuperposing leg.

The trays 10 and 11 are ordinary wire trays, such as the ordinarylettertrays for use on desks, which trays it is frequently desired tosuperpose one upon the other to make a multiple tray of any desirednumber of stories.

I superpose these trays by detachable wire legs 12, one at each corner,extending between each lower tray and the next higher tray. Eachsuperposing leg 12 is made of two strands of wire twisted together toform an intermediate part 13 of considerable strength. At the lower end,the two strands of each-leg are separated to form a fork 14, the prongsof which are detachably insertible into two vertical sockets 15 formedin a sheet-metal corner piece 16, which is clamped on each corner ofeach tray which may at any time be a lower tray, preferably beingprovided at each corner of all the trays so that they may be superposedin any order. These sheetmetal corner pieces 16 are clamped in place bybeing provided with ears 17 which are bent around the upper wire 18 ofthe tray on the two sides forming the corner and close to the corneritself, as is clear from Fig. 3. At the upper end of each detachable leg12 the two strands thereof are separated to form two fingers 19 and 20,the

latter longer than the former. The finger 19 hooks obliquely over thetwo longitudinal and transverse wires 21 and 22 of the tray bottom whichcross each other closest to the bottom corner of the tray and are bentupward to be looped around the top wire 18 of such tray. The fingerobliquely beneath such CIOSSlIlg point of the wires 21 and 22, andprojects to the next inward crossing point 23-the first crossing inwardfrom both wires 21 and 22-and is there provided with an upturned end 24:which may be sprung over such This sprung condition holds the leg 12firmly in place with respect to the upper tray 11. The prongs of thefork 14; are also slightly sprung where they proi'ect into the sockets15, so that they grip suc1 sockets 15. This makes a firm connection ofthe leg 12 with the lower tray. By these firm connections of the legs 12with both the upper tray and the lower tray, the two trays are heldrigid with respect to each other, and it is even possible to lift thewhole tier of trays by grasping merely the upper one, as the connectionis so firm that the lower trays will hang from those above. Theconnections of the legs to both the upper and lower trays are easilyattachable and detachable, so that the tiers of trays may quickly.

I claim as my invention:

1. In combination, two trays, superposing legs for interconnecting suchtrays, each of said legs being provided with hooked portions for hookingobliquely over and under wire crossings at the corners of the upper trayand being provided at its lower end with two separated prongs, anddoublesocketed members attached to corners of the lOWer tray forreceiving the prongs at the lower end of said superposing legs.

superposing leg for cooperating with other similar legs to superpose onewire tray upon another, comprising two wires twisted together at anintermediate portion and separated at their ends, the lower separatedends being arranged as two prongs, and the upper separated ends beingarranged as books for ooking over and under two obliquely-relatedcrossings of the bottom of the upper tray, in combination with adouble-socketed member attached to a lower tray for receiving said twoprongs.

be rearranged easily and 3. A superposing leg for cooperating with othersimilar legs to superpose one wire tray upon another, comprisin twowires twisted together at an intermediate portion and separated at theirends, the lower separated ends being arranged as hooks for hooking overand under two obliquely-related crossings of the bottom of the uppertray, in combination wlth a double-socketed member attached to a lowertray for receiving said two prongs, the upper hooked portion which hooksbeneath a crossing in the tray bottom being provided with a bent endwhich may be sprung over such crossing to hold the leg in place. p

In witness whereof, I have hereunto set my hand atLa Fayette, Indiana,this 19th day of April, A. D; one thousand nine hundred and twenty one.
